Automatic sugar dispenser



g- 1933- H. v. STANFIELD 85 AUTOMATIC SUGAR DI SPENSER Filed May 6, 1952 [Z w J L \w l l\ I F Inventor #277 1 53 a ry 'e/a a waai ih of the part B fitting Patented Aug. 15, 1933 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to an automatic sugar dispenser, the general object of the invention being to provide means for dispensing a certain amount of sugar or the like when the container provided with the invention is inverted.

This invention also consists in certain other features of construction and in the combination and arrangement of. the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts through the several views, and in which:-

Figure 1 is a sectional view through a part of the container provided with the invention.

Fig. 2 is a section on line 2--2 of Fig. 1.

In this drawing, the letter A indicates the container and the letter B indicates a cap threaded or oth rwise detachably connected with the upper end of the container.

A tapered dispensing neck 1 fits in an openingin the part B and is held therein by the flange 3 in a groove 4 formed in the lower end or" the body part 1 and the upper or outer end of the part 1 is formed with a mouth 5 having a reduced inner part 6 which forms a seat for a valve 7 the stem 8 of which passes through the guide 9 carried by the spider 10 located in the lower part of the member 1 and a valve plate .il is connected with the lower end of the stem as shown at 12. The lower end of the member 1 is rounded to form a seat 13 for the valve plate 11.

A plate 14 has its ends bent to engage the lower end of the member 1 with the bight portion of the plate acting as a baflle. This plate 14 is narrow so that it will not interfere materially with the passage of the contents of the device into the neck 1 for the engagement of the contents with the valve '7, when the device is inverted. A spring 15 encircles the lower end of the stem and bears against the spider and the valve plate 11 and tends to hold the valve 11 open and the valve 7 closed.

Thus it will be seen that when the device is in operative position the valve 7 will be closed so that insects, dirt and dust cannot enter the member 1 and contaminate the material in the container. When the device is turned upside down, some of the contents will pass the valve 11 and pass through the member 1 and drop upon the valve '7 and when an amount of material collects on the valve 7, to weight the same to an amount greater than the tension of the spring 15, the valve 7 will open and the valve 11 close so that the material in the member 1 will drop from the device into a cup or other receptacle over which the device is placed.

Thus by adjusting the spring, a spoonful or any desired amount of material can be dispensed each time the device is inverted. By providing the reduced part 6, the material will continue to flow from the device while the valve 7 is closing.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having thus described my invention what 1' claim as new is:-

l. A device of the class described comprising a container, a cap detachably connected therewith, a neck member connected with the cap, a valve at each end of said neck member, a valve stem, connecting the two valves together, and a spring for normally holding the outer valve on its seat and the inner valve open, the relationship between. the tension of the spring, the area of the outer valve and the capacity of the neck member being such as to cause the weight of a certain amount of material resting on the outer valve to overbalance the spring and open the outer valve and close the inner valve.

2. A device of the class described comprising a container, a cap detachably connected therewith and having a neck member connected therewith having a mouth in its outer end formed with an inner reduced portion forming a valve seat, a valve seat formed at the inner end of the neck member, a stem, a spider for guiding the stem, a valve at each end of the stem, a spring between the spider and the inner valve for normally holding the outer valve on its seat and the inner valve off its seat, the relationship between the tension of the spring, the area of the outer valve and the capacity of the neck member being such as to cause the weight of a certain amount of material resting on the outer valve to overbalance the spring and open the outer valve and close the inner valve.

3. A device of the class described comprising a container, a neck member connected therewith having valve seats at its inner and outer ends, a stem movably arranged in the neck member, 'a valve in each end of said stem, and a spring for normally, holding the outer valve on its seat and the inner valve open, the relationship between the tension of the spring, the area of the outer valve and the capacity of the neck member being such as to cause the weight of a certain amount of material resting on the outer valve to overbalance the spring and open the outer valve and close the inner valve.
